First Alert's innovative OneLink system allows multiple smoke and carbon monoxide alarms to be interconnected wirelessly. This combination smoke and CO alarm offers First Alert's exclusive new Voice Warning System with Location Alert which allows you to set multiple alarms with a location. When an alarm is sounded the interconnected system will alert you which room has a potential hazard that is setting off the alarm. If smoke is detected in the basement all of the wireless alarms will say "Warning Evacuate Smoke in Basement."
Alarms that communicate with each other may provide earlier warning of a potential danger as compared to single stand alone alarms. With the ease of wireless connectivity you can have a network of alarms setup in minutes.
